Circuit/System Testing
- Identify how to disable high voltage.
- Identify how to test for the presence of high voltage.
- Identify condition under which high voltage is always present and personal protection equipment (PPE) and proper procedures must be followed.
- Perform the High Voltage Disabling procedure.
- Remove the 3-phase cables from the K59 Starter/Generator Control Module.
- Test for infinite resistance between each of the 3-phase circuit terminals listed below and ground:
- X3 phase U terminal A
- X3 phase V terminal B
- X3 phase W terminal C
- If less than infinite resistance
Test each phase of the drive motor generator 3-phase cable for a short to ground.
- Go to next step: If infinite resistance
- Replace the component: A15 Starter/Generator and retest for the DTC.
- If the DTC sets
Replace the component: K59 Starter/Generator Control Module.
- Go to next step: If the DTC is not set
- If the DTC sets
- All OK.
WARNING:
Always perform the High Voltage Disabling procedure prior to servicing any High Voltage component or connection. Personal Protection Equipment (PPE) and proper procedures must be followed.
The High Voltage Disabling procedure will perform the following tasks:
Failure to follow the procedures exactly as written may result in serious injury or death.
